D-Sub Connectors

The D-sub connector family is a widely used group of connectors with metal shells and multiple contacts. The metal shells provide shielding against RF interference and mechanical stability. The connectors are divided into the categories of D-subminiature (“D”-sub or Mini-D), HD, and HD-plus, depending on the size and the type and number of contacts.

The CWR-283-25-0000 connector is an example of the D-sub family. It is a 25-pin miniature D-subshell with a 2 – 4mm depth and a female receptacle. It has an integrated mounting bracket.

Applications

The CWR-283-25-0000 D-sub connector is typically used in computer peripherals, such as keyboards, mice, and joysticks. It is also used in medical equipment, test equipment, televisions, monitors, and other consumer electronics. The connector is able to meet the requirements for shielded applications thanks to its metal shell.

Working Principle

D-sub connectors are constructed from an outer metal shell, a dielectric, and various contacts. The metal shell provides a static ground and protects the connector from EMI/RFI. It also provides a reliable connection to the mating device. The dielectric provides insulation between the shell and the contacts, protecting the contacts from electrical damage.

The contacts in the connector are typically made of copper or aluminum alloy and are plated with gold or nickel. Contacts are available in variety of shapes and sizes, such as pins, sockets, and shields. The contacts are simply pressed into the female shell and held in place with an inside snap ring or lanyard. The contact pins of the D-sub connector are normally connected directly to the printed circuit board when in use.

Conclusion

The CWR-283-25-0000 D-sub connector is a rugged and reliable 25-pin connector with an integrated mounting bracket. It is suitable for use in a variety of applications, such as computer peripherals, medical equipment, test equipment, televisions, and monitors. The contacts are typically made of copper or aluminum alloy and are plated with gold or nickel. They are held in place by an inside snap ring or lanyard. The metal shell of the connector provides shielding against RF interference and mechanical stability.
